Mid-range smartphones, or “uberflagships,” as Russian tech journalists dubbed them, are perhaps the best thing to happen to the mobile industry in 2016. Rapid progress has led to the fact that mid-range smartphones are now so good that they quite successfully satisfy the needs of even very demanding users.

Samsung Galaxy A5 (2017)

CPU: Exynos 7880 Octa
RAM: 3 GB
Memory: 32 GB
Display: 5.2" Super Amoled 1080 x 1920
Camera: 16 MP, f/1.9 (main), 16 MP, f/1.9 (front)
Battery: 3000 mAh
Size and weight: 146.1 x 71.4 x 7.9mm, 157g

Roughly speaking, modern flagships are superior to mid-range devices only in the camera level, as well as various innovations such as a fingerprint scanner, heart rate sensor, screen pressure detection, improved sound path, fast wireless charging and others. Such technologies first appear in flagship devices and only the next year become available in mid-range devices.

In this plan samsung galaxy A5 (2017) is made, as they say, according to classic patterns and is similar to the flagship of 2016 years of samsung Galaxy S7.

The case is made of impact-resistant Gorilla Glass with an oleophobic coating. The smartphone received a curved back panel and slightly rounded edges (2.5D) screen glass.

The Galaxy A5 features a Super Amoled display, water and dust protection according to the IP68 standard (up to 30 minutes at a depth of up to 1.5 m).

The device also supports such fashionable "chips" as Always-on display, payment Samsung service Pay, technology fast charging and others.

Design and screen

Externally, the Galaxy A5 (2017) really looks like the Galaxy S7 and looks, as marketers would say, no less premium than last year's Samsung flagship.

Dmitry Bevza/Gazeta.Ru

The display is made according to super technology Amoled, diagonal - 5.2 inches, resolution - Full HD (1080 x 1920). This is a bright and contrasting screen with wide viewing angles and deep blacks.

At the same time, the display of the Galaxy S7 had more a high resolution- QHD (1440 x 2560). Oddly enough, such a reduction turned out to be quite a good decision. If you do not insert the Galaxy A5 into a VR helmet, where QHD is easy necessary minimum, then for the diagonal 5,2 Full permissions HD is enough.

Battery and processor

Importantly, a lower resolution screen is not only cheaper, but also consumes less power. By time offline Galaxy works The A5 (2017) is clearly superior to the Galaxy S7. Although Samsung does not position the device as a special long-playing device, moderate power consumption is one of its strong points.

And for at least a year, you'll be able to play the most graphic-demanding games.
Support for fast charging is an added bonus.

Camera

Taking photos is where the Galaxy S7 analogy doesn't fit. Last year's Samsung flagship has one of the best to date mobile cameras and certainly a pity that she did not migrate to the A5.

The smartphone has a completely different photomodule: a 16 MP camera with f/1.9 aperture. For comparison, the Galaxy S7 has a 12MP camera with f/1.8 aperture.

You shouldn't think that large quantity matrix pixels will provide better quality pictures. A lot of other parameters also matter, such as aperture ratio, pixel size, autofocus operation, stabilization, processing algorithms.

Dmitry Bevza/Gazeta.Ru

Especially Galaxy camera A5 loses in low light. If in photographs taken during the day and even at dusk, the difference in quality is not very noticeable, then when shooting at night it is still fatal.

Perhaps the point is in the algorithms for processing night shots and in the absence optical stabilization(OIS). If in future firmware updates software part developers can still fix it, then you will have to put up with the lack of OIS.

Note that

Galaxy A5 (2016) had optical stabilization, and why it was abandoned is a mystery.

And here front-camera with 16 megapixels is designed to please selfie lovers. To her, unlike the main one, there are no complaints.

"Chips"

What is interesting about the Galaxy A5 that makes it stand out from the competition?

Water and dust protection distinguishes the Galaxy A5 (2017) from other competitors. Only smartphones can boast similar durability. Sony Xperia. Of course we are talking about ordinary smartphones, and not about special devices for extreme sports and the military.

The fingerprint scanner can be configured to recognize up to three fingerprints. The technology works quite correctly, but still slower than in the Galaxy S7. It is worth paying attention to the fact that the scanner is combined with the Home button.

For Android-smartphones, such an "iPhone" location of the scanner is a rather rare option.

Samsung Pay in a sense, a unique, although not the most requested option, which is only in new Galaxy smartphones S and Galaxy A.

Especially for the paranoid, there is a safe KNOX environment. That is, private information can be stored in a special encrypted folder.

Always On Display finally appeared not only on Samsung flagships. The essence of the function is that the time, calendar and notifications are shown even when the screen is off. At the same time, the battery is consumed a little faster, but the Galaxy A5 (2017) still lives its two days with the Always On Display option activated.

And the last important little thing lies in the fact that the device does not have a hybrid slot for SIM cards and memory cards, but there are two separate full-fledged holes.

That is, you can insert two SIM cards and a memory card at the same time. Given that the A5 has only 32 GB of main memory, this is more than a justified decision.

Outcome

Of the obvious advantages of the Galaxy A5 (2017) - the spectacular design of the flagship S-series, high-quality screen, long battery life battery life, 16 MP front camera, waterproof and dustproof according to IP68 standard.

Of the less noticeable - support for Samsung Pay, well-developed proprietary GUI, simultaneous support for two SIM cards and a memory card, branded accessories, high-quality assembly, warranty, technical support and other things that stand behind big brands.

Cons - the operation of the main camera in low light conditions, the lack of optical image stabilization in the camera, the lack of wireless charging, and still the rather high price of the device (28 thousand rubles), which is declared as a budget flagship.

Nowadays, a person without a smartphone is a person out of touch with life. It is hard to imagine that a few years ago the mobile phone was used only for communication. Now this little helper gives us both access to the Internet and many applications, and wakes us up in the morning. The list of benefits provided by a smartphone is endless. It is not surprising that a large number of gadgets have been invented for modern phones. One of them is a wireless charger, which we would like to talk about in more detail.

How to determine if the phone supports wireless charging?

From the name it is clear that this is a gadget that allows you to charge your smartphone without using wires. It is a small stand connected to the network. Inside there is an induction coil, which creates a small magnetic field around itself. If there is a smartphone within the radius of this field, it will receive electricity in the truest sense of the word through the air. But there is one caveat - the induction coil must also be built into the smartphone. It will serve as a kind of energy receiver from the charger.

The purpose of this device was to get rid of modern smartphones from charger sockets, as well as allow all devices in the house to be charged from one platform. The idea was a success, but why then do we not see this technology in every home and do not use it ourselves? The answer is simple - despite all the advantages, this miracle device also has disadvantages.

Pros and cons of a wireless charger

There are enough advantages to wireless charging, but they all have their cornerstone.

No wires

Without a doubt, this is a big plus. Wires have always been a weak point in chargers. With frequent kinks, the wire was easily damaged and tangled. Frequent recharging loosened the USB port in the phone, and sooner or later a repair was required. But there is also the other side of the coin. The rejection of wires reduced the efficiency (coefficient of performance) from 90% to 60–75%. Simply put, when using wireless charging, your smartphone will charge for about 2-3 times longer.

Range of use

It would seem that there are no wires - there are no restrictions, and you can charge your phone just being in the apartment. But no - the range of using a wireless charger is very modest (3-5 cm) and the phone will have to be placed on a stand. Another significant drawback will be the impossibility of using a smartphone while charging.

Price

The cost of the charger is quite variable, but it will always be more expensive than the charging we are used to.

Standards

I would like to talk about the standards that made the use of electricity transmission technology over the air possible.

Qi ("Qi", in honor of the term of Eastern philosophy) was developed by WPC (Wireless Power Consortium - Consortium of Wireless Electromagnetic Energy). It is the most widespread and is supported by such giants of the mobile industry as Asus, Motorola, HTC, Huawei, LG, Nokia, Samsung, Blackberry, Sony and others. You can learn more about the standard and the list of supported devices on their official website.

The PMA standard also uses the principle of electromagnetic induction, but cannot boast such a large list of manufacturers supporting their technology as Qi. It was developed by Powermat, which this moment trying to fight unhealthy competition from Qi.

This standard uses Rezence technology, which is fundamentally different from PMA and Qi. The strange thing is that the most unpopular standard has many advantages over its competitors. The pluses include:

• the ability to charge through interference (if you put a book between a smartphone and a charger, nothing will change);
• one platform can power multiple devices;
• work in close proximity to metal objects, etc.

Acquainted with complete list smartphones that can use wireless charging right out of the box can be found on the official website https://www.wirelesspowerconsortium.com. I would like to note that most of the manufacturers made sure that their product supported the use of this technology.

What if your smartphone is not on the list of supported devices, but you need to use wireless charging? If you have such a question, then most likely you are a happy user of Apple products. So far, the iPhone does not provide the ability to receive electromagnetic signals. However, there is an alternative - the purchase of an auxiliary accessory that will do this for your phone. It fits under a standard case and does not cause any discomfort.

Is wireless charging harmful to health?

Like any new technology, the wireless charger raises a lot of questions. One of the most acute is whether it is harmful to health. Let's dispel this far-fetched myth. It will do you no more harm than an electronic shaver using the same technology. This is also claimed by the developers of the WPC standard themselves.

We hope our article was useful and helped you figure out the compatibility of your smartphone and wireless charger.

Team A is back in action. At least when it comes to the company Samsung and a new reincarnation Galaxy A5 sample 2016 of the year . The smartphone wants to be like the S6, but it's much cheaper and has some premium features at the same time.

Models Galaxy A for 2016 is the answer Samsung on the trend of Chinese manufacturers to produce premium smartphones at an average budget price. This makes the smartphone a competitor OnePlus X And Xiaomi Mi 4c as well also an alternative Galaxy S6.

What is the new Galaxy A5 2016? Let's take a closer look.

Key features:

- available with a hybrid slot that allows you to use either two SIM cards or a SIM card and a memory card;

- a metal frame sandwiched between 2.5D and Gorilla Glass 4;

– 5.2 inch display with type Display Super AMOLED with a resolution of 1080 × 1920 pixels and a density of 401 units;

- octa-core Snapdragon processor 615 (also available with Exynos 7580); 2 GB random access memory and graphics chip Adreno 405;

– OS Android 5.1 with proprietary firmware TouchWiz;

– 13 MP main camera with automatic image stabilization and the ability to record video in 1080p;

- 5 MP front camera with 1080p video recording;

– 16 GB of built-in memory + 8 GB can be added via a memory card;

- Fingerprint sensor and instant payment system Samsung Pay;

- 2900 mAh battery.

Main disadvantages:

– there is no possibility to record video in 4K or 1080p at 60 frames per second;

– limited memory space. There is no 32 GB version. But more depressing that you can only add 8 GB on a removable card;

– no MHL (but USB OTG is supported);

The whole summary boils down to what needs to be compared this smartphone with the Galaxy S6, since the company is positioning this gadget as its replacement. And then it turns out that the smartphone is not quite up to par, although it received some bonuses in the form of MicroSD and FM radio, which the flagship does not have. But the camera received a lower resolution - 13 megapixels versus 16 megapixels. And 1080p video vs 2160p. The gadget also received a more capacious battery - 2900 mAh versus 2550 mAh, but lacked the ability to wirelessly charge. He also missed the screen resolution - 1080p, not QHD. But I got a slower chipset with less memory: 2 GB versus 3 GB. There is no heart rate sensor and blood oxygen sensor.

As technical conclusion hard to understand why Galaxy A5 2016 should replace the Galaxy S6. It's a completely different phone low level. The only thing better is the battery size. The camera is frankly weak, weak processor, little memory and RAM. Compared to the flagship of the first generation, of course.

This is despite the fact that original Galaxy The 2014 A5 was an ambitious project that offered an outstanding set of circuits for affordable price. BUT new smartphone only offers Samsung Pay. Internally, but externally, he has not changed at all.

Package

The Samsung Galaxy A5 (2016) is offering a retail package of 15W fast charger and MicroUSB 2.0 cable, and three-button headset remote control. That is, nothing in the configuration has changed.

We take the Samsung Galaxy A5 (2016) in our hands and measure it with a ruler - 144.8 × 71 × 7.3 mm. Weight - 155 g. This makes it larger and heavier than the Galaxy S6. And the point is not even in size, but in weight - 138 g weighs S6).

Equipment overview

What is your favorite snack on a premium phone? Sandwich made of glass and metal as a body, of course! This is the most popular combo after the full metal jacket. So, Samsung Galaxy A5 (2016) still received new class protective glass Gorilla Glass 4. The flagship S6 has the same one.

The metal sides are bevelled with small nubs on each of the four corners that improve traction and give a more secure grip on slippery surfaces.

The bezels around the screen are average, but Samsung's designers have created the illusion of very thin bezels. To do this, they used black glass and slanted metal sides to hide the extra thickness.

In the hand, the A5 (2016) feels like an impressive device. We are used to mid-range phones of this size being lighter in weight. It's not good or bad, just an opinion.

What's really good is the new screen resolution. The smartphone has been upgraded from 720p to 1080p. Add here the appearance of a fingerprint sensor on home button. Let this be the first wave sensor, the cheapest and not the most convenient, but now it is. It remains only to regret that it is not behind.

What's bad - the touch control keys have lost the possibility of long-term illumination. Apparently, in order to save battery power, which has already grown in volume. But they improved the capabilities of the selfie camera to help the user with night photos.

Bevelled Gorilla Glass 4 on the front and rear panels creates a beautiful curve that continues into the metal frame. The technology is now much more pronounced than on the Galaxy S6, and the phone feels better in the hands after this treatment.

On the sides are the standard power and volume buttons, as well as slots for a nano-SIM card and MicroSD. The metal frame is not very thick, which leaves little room for the buttons. They are narrow.

A slightly rough surface appeared on the back. The back is available in black, white, gold, or pink, while the front is almost always painted black (aside from the white version). The metal on the sides matches the back.

The 13-megapixel camera may not have an S6 sensor, but it does have its own F/1.9 wide aperture and auto image stabilization. And she doesn't stick out. One single-color LED flash goes into the bargain. There are no heart rate or blood oxygen sensors next to it, like the S6.

At the bottom of the phone is a microUSB 2.0 port and a loudspeaker (hidden behind a grill in drilled holes). There is also a microphone on the top and bottom – this pair is used for noise cancellation and stereo sound recording.

Final words

The result is a strange conclusion. Design Samsung Galaxy A5 (2016) turned out even better than the flagship S6, but inside technical novelty is inferior to competitors who have long been able to shoot video in ultra-high resolution and have QHD screens. So technically Samsung doesn't surprise the consumer too much in the middle segment. But if you need beautiful phone- This gadget can be an excellent choice.

A technology has now become available that allows you to charge phones without using a cable. Its advantage is that this procedure is faster and easier, and you do not have to connect your smartphone to the network every time - just place the device on top of the wireless charging pad.

There are various competing standards for this technology. The most popular of these is Qi, which is today backed by companies such as Samsung, Google, and Nokia. However, more and more manufacturers are starting to use it in one form or another.

Which phones support wireless charging?

Some smartphone models have a built-in wireless charging function (their rating is presented below). Other devices will need to be replaced for this. back cover or corps. Components for Qi are produced for specific phones, so if you connect them yourself, you should make sure that you select a compatible model.

If a dedicated wireless charging cover is not available for your smartphone, you can use a universal adapter that allows you to use this technology even for older devices.

What do you need to know about wireless charging?

As noted above, the current leader is the Qi standard, which is currently used in most Android devices. The technology works by using magnetic induction to allow energy to be transferred from the platform to the phone's battery. The Qi standard, whose name in Chinese means "air" or "spiritual energy flow", was created in 2008 and began to be developed simultaneously with the participation of 206 companies, including Microsoft, Samsung and Sony.

Speaking about which devices support wireless charging, we should also remember about the less common PMA standard. It also works due to magnetic induction, but its distribution area is somewhat lower. In June 2014, the developers of the PMA standard partnered with Duracell to place charging platforms in some public places in the US to promote the technology. If this idea proves viable in the future, it is possible that more smartphone manufacturers will start using this standard.

If we talk about which phone models support Qi-standard wireless charging, then the choice will be very large. Even if your Android smartphone doesn't have this technology built in, you can get a universal Qi receiver that only costs about $15. Despite the bulkiness, it will add significant convenience to you when using the gadget. The device attaches to the back of your device, which can then be placed on any Qi-compatible charging platform. When it comes to which phones support Qi wireless charging, there is a receiver for the iPhone (models 5, 5s, and 6) that is also getting positive reviews. Its cost is about 30 dollars.

Which phones support wireless charging (list of gadgets)

Those who are interested in the new technology will find it useful to know the rating of devices that have built-in Qi standards.

The best known model in this regard is the one which is currently available for around $200. According to user reviews, this is one of the best devices Basically Android. Also, this device is a leader in the use of wireless charging. The smartphone is compatible with both Qi and PMA technologies. With its elegant design, good performance and large 16-megapixel camera, this phone outperforms the iPhone in some ways. Commercially available Qi memory has a good long cable for connecting to the network. Its edges are illuminated with a light blue tint during charging and turn green when it is completed.

Among the devices that can charge wirelessly are the following:

• Samsung Galaxy Note edge.
• Samsung Galaxy Note 4.
• Google Nexus 6.
• Motorola Droid Turbo and others.

Other Samsung models

Analyzing which Samsung phones support wireless charging, one cannot help but remember about this model. This model also simultaneously supports both standards - both Qi and PMA. The attractive curved body shape and comfortable screen allow owners to instantly access messages and other important data, and the built-in adapter does not impair the use of the device in any way. If the gadget itself can be purchased for about $300, the cost of the Pad to charge would be about $40.

Also belongs to this category of devices. This smartphone with an innovative curved screen offers very strong graphics performance on a bright display. Its screen size is much larger than other devices, so the battery consumption is correspondingly faster. In this model, the wireless charging capability is not integrated directly into back phone, but there is a special Samsung cover with Qi support that replaces the standard back of the device. This accessory costs approximately $25 and is available in two color options: jet black and snow white.

If you ask which phones support wireless charging in general, you will notice that this technology mainly affects gadgets with high hardware capacities, for which the ability to quickly charge them is especially important.

Based on this, it is not surprising that it is also equipped with the described technology. This gadget is highly multitasking, fast and quality camera and high brightness screen, having a size of 5.7 inches. In order to carry out its wireless charging, you will need a special case. It's available for around $30 and comes in two colorways.

However, Samsung is not the only manufacturer to massively use this technology. Which phones from other brands support wireless charging? Consider below.

Other brands

Google Nexus 6 has a nearly 6-inch screen and is equipped with a high-powered processor, so it especially needs the ability to quickly and quickly recharge. Qi technology is built in from the start, so there is no need to buy an additional cover or case. This gadget is quite expensive - about $ 500, but fans highly appreciate its hardware power along with Android 5.0. All this offers users high level comfort. Although there is no dedicated wireless charging platform, a universal accessory will do the job just fine.

Speaking about which phones support wireless charging, one cannot but touch upon a model such as the Motorola Droid Turbo. This smartphone with a screen of just over 5 inches has a camera with a resolution of 21 megapixels and many built-in features. Its battery life is approximately 9 hours under active use, so the built-in Qi technology is very useful. There is also a special charger for this model, which places the phone in a vertical position. This means that while charging, you can continue to use the device.

Sony brand

As already noted, the most active new technology used by manufacturers such as Samsung, Google and Sony. What kind Sony phones support wireless charging? First of all, this is the Sony Xperia Z3 - a waterproof gadget that, with active use, works up to 12 hours without recharging. Its screen is high brightness, and the speakers provide loud chic acoustics. Despite the fact that its cost is about $ 400, the device is very popular. The wireless charging cover will have to be purchased separately and costs over $100.

Can you adapt your smartphone?

What phones support wireless charging without built-in technology? If your device does not natively support Qi, you can separately purchase and install an adapter on it and use the universal wireless charger. Depending on the brand of the gadget, you can connect the adapter via the micro-USB port (on the Android platform) or lightning (on the iPhone).

Universal wireless charging adapters

If your phone is not listed above, then you need a universal adapter and wireless charger. You can get them for phones with micro USB ports (like Android) and lightning ports (like iPhone). Thus, you can update and improve almost all devices available for sale. If we talk about, for example, what Xiaomi phones support wireless charging, then with the above method you will be able to charge without a cable even a 5-year-old model.

Universal charger

Once you've made sure your phone supports wireless charging (by built-in functionality, using a special cover, or by connecting an adapter - it doesn't matter), you need to purchase a wireless charger.

Currently, there are many such Qi devices available in various sizes, shapes and colors. You can buy such a component not only for use at home or in the office, but also for a car, and even portable accumulator qi. If you have purchased a smartphone that supports wireless charging, it is advisable to choose a charger specially designed for it. If there is none, or you updated your gadget yourself, search universal device won't be difficult.

• 1. What is Qi wireless charging

  The world is becoming mobile and "wireless".

  IN modern world all manipulations with file transfer using a smartphone happens "over the air". Internet access via wi-fi - at home, at work, in a cafe is taken for granted, and rarely anyone has difficulty using it. The time has come forwireless power transmission.

  In 2008 was founded " Wireless Electromagnetic Energy Consortium" (Wireless Power Consortium, WPC), which brought together manufacturers from Europe, Asia and America. The goal of the "Consortium" is to develop a single standard for wireless charging technology.

  Already in 2009 the company Palm provided the first phone to support wireless charging. Later, in September 2012, Nokia introduced 2 smartphones to the market - Lumia 820 And Lumia 920 also with qi standard support. Next, major smartphone manufacturers pulled up - Samsungg, Google Nexus(Asus, LG), Sony, etc.

  Since 2014, our company Zaryadqi has been developing and distributing wireless chargers in Russia. In our store the most big choice wireless chargers and we are constantly monitoring new products and expanding our range. You will definitely find the right charger for you in our store.

• 2. Working principle

  In plain language:

  • The charger is connected to a power source.
  • A magnetic field is created.
  • The smartphone must support wireless charging - have a built-in receiver or the receiver is installed additionally.
  • The phone is placed on the charger.
  • Smartphone charging starts automatically.

  From a technical point of view:

  Energy is transferred from the transmitter to the receiver-receiver through an interconnected magnetic field generated by the flow of alternating current through the transmitter coil.
  If the receiver coil is in close proximity, a significant portion of the transmitter's power lines will pass through the receiver coil, creating an alternating current in the receiver, which is then converted to a DC voltage.

• 3. Benefits

  Just. Put your smartphone on the Qi wireless charger and it will start charging automatically.

  Modern. All major IT companies are already developing their devices according to the Qi standard.

  Universal. Any device with a Qi receiver-receiver is charged by any Qi wireless charger.

  Safely. The generated electric field is safe for humans and extends only 1 cm from the device.

  Comfortable and convenient. There is no need for a bunch of wires that later get tangled or simply lost.

• 4. Phone models that have a built-in receiver-receiver and support wireless charging out of the box

  More and more smartphone manufacturers are starting to build receivers into their top models: Apple iPhone XS, XS MAX, XR, X etc, Samsung Galaxy S9/S9+/Note 9, Xiaomi Mi Mix 2S, Huawei Mate 20 Pro and etc.

• 6. How to use wireless charging

  

• 7. Types of wireless chargers

  We conditionally divide wireless chargers into several types according to their functionality:

  • . Standard charging stations in the form of a small "platform" on which the phone is placed, or charging built into appliances - a lamp, a watch, weather station and etc.
  • . Wireless charging for use in the car: with special holders and brackets for the phone and adapters for the cigarette lighter.
  • . Wireless chargers with stand function, i.e. The phone is at an angle during charging for convenient viewing of video, mail, social networks.
  • . Wireless chargers with a built-in battery differ among themselves, in addition to design, in the number of additional usb ports and battery capacity - from 4000 mAh to 10000 mAh.
  • . Wireless chargers for embedding in tables, cabinets, bar counters. They have a special design and protection against moisture and dust.

  And also by scope or place of use:

  • Home / office
  • In the car
  • On the way
• 8. There are receivers
  • Embedded- already installed in the smartphone by the manufacturer.

  If the manufacturer of your phone has not provided for the possibility of wireless charging, it can be easily adapted to this charging! For this, a special receiver film is used - there are several types of them:

  • In the form that is installed under the cover of the smartphone. To do this, the phone must have special contacts.
  • , which connects to the lighting power port on Apple and micro-usb on Android smartphones.

  Image	Description
  	The film is attached under the cover of the phone, the functionality of the phone is not reduced. The standard cable can be used at the same time as the receiver film is installed. Such receiverqifor phones with special contacts suitable for phones that have special contacts for wireless charging: Samsung Note 4, Samsung Note 3, Samsung Note 2, Samsung Galaxy S5, Samsung Galaxy S4, Samsung Galaxy S3 and more.
  	The film is attached to the back of the phone. At the same time, it can be closed with any standard cover: made of leather, plastic, silicone - this will not affect the charging process. The connector, which is inextricably linked with the film, must be in the Lightning connector for Qi charging. The presence of a film receiver does not cause inconvenience. Such Apple-receiverqi Suitable for Apple devices with Lightning connector: Apple iPhone 5, 5s, 5c, 6, 6s, 6Plus, 6SPlus, SE, 7, 7 Plus; iPad Air 2, iPad mini and others (Apple does not currently support wireless charging without accessories)
  	Such universal receiverqi Suitable for any phone equipped with a USB connector for classic wired charging. The film is attached under the cover or case of the smartphone. The plug, inextricably linked with the film, for charging according to the Qi standard must be in the Micro-usb connector. The presence of a film receiver does not cause inconvenience.

  On phones with a Micro-USB port, the connector can be one of three types, depending on its appearance, when you put the phone on top of the screen.

  Connector type "C" appeared relatively recently - it can be found on a few devices. So, type "C" is equipped with MacBook 12", Samsung TabPro S, Google Nexus 6P, Microsoft Lumia 950XL, ZUK Z1, Google Pixel C, Google Nexus 5X, One Plus 2, Acer Aspire Switch 10 V and other devices.

  In addition to the above receivers, depending on the location of the connector in the phone, such film receivers may be suitable - they are called lateral or offset:

  

  Accordingly, each type and position of the connector needs its own Universal receiverqi. By identifying the correct type of Micro-USB connector in your phone, you will buy the right receiver for wireless charging and allow yourself to forego wires!

  • There are also: the receiver is already built into the case, so just put the case on your phone and it will be able to charge wirelessly.

  

  You can always tell the manager of the online store your phone model - we will select the best receiver for you!

• 9. Difference between wired and wireless charging

  Wireless charging produces a current of 1 ampere and a voltage of 5 volts. The standard power adapter that comes with the smartphone gives out from 1 to 2A. And when charging the phone from a computer (USB port), the phone is charged with a current of 0.5A (USB 2.0) to 0.9A (USB 3.0).

  In this regard, you will not even feel the difference in charging time, or it will not be significant.

• 9. Energy efficiency

  The energy efficiency of Qi wireless chargers is approximately 80%. It should be understood that it is simply impossible to achieve 100% energy efficiency; for standard wired chargers, this figure ranges from 75% to 95% at best.
